摘要
Pyrite in Xuekong-Luolu area occurs in the bottom of Longtan formation of Upper Permian,for the ore-bearing assemble lithology it can be divided in to clay pyrite and carbonaceous shale type pyrite,clay pyrite distributes stably and is controlled by lower Maokou formation karst wavy plane,the thickness of carbonaceous shale type pyrite changes a lot and occurs as like-layered and Lentoid.Its mineralization mechanism is formed by sulfide of rich organic in perched oxygen deficient water and Iron ions in sedimentary clastics,the deposit genesis is beach closed lake sedimentary pyrite.
